I work in an oil refinery. I use these radios to communicate with my crew.. the volume is loud enough and very clear.
Impressive Range: Clear signal even over hills or around buildings.
They work well. The range is good too. No problems.
It works just like the rest of them. No problems yet
I bought these so my 6 yr old grandson could talk to the kids across the street. (we gave them a set too) The conversations are clear and they are having a blast with them. The only thing is the channel changer is easy to hit. There is not a display for the channel setting so if the button gets hit, make sure you listen for the automated voice to say which channel you changed to. Then change it back. The charge is holding up really well. So far, they are on day 4 of semi-continuous use. They also charge quickly. Enjoy.
already opened up, and using on patrol now, security, so far love it, I ordered other one's, but was alot of Xtra stuff, that I didn't care to invest time learning, these work perfect so far, volume is easy and literally ready to use, very basic and simple for us, picture shows. Would have done 5stars, but was supposed to arrive by 8am, I went to bed at 9am, for my 3pm shift,
So easy and fun to use! Even my kids figured it out instantly.
